摘要大型轴瓦车床是用来车大型轴瓦的内球面和外球面以及大型轴瓦上面的圆柱孔和槽和端面的一种机床。本课题是要求我们设计一个可以加工大型轴瓦的简易机床。给我定了两个电动机，一个是主电机还有一个是快速电机。我想设计的是，将主电机和联轴器连接起来带动机床上面的齿轮传动，从而实现加工大型轴瓦的内球面的效果。然后再画两个辅助工具，用于加工大型轴瓦的外球面和圆柱孔和槽和端面。这样这个整体的设计就结束了。具体的方案设计会在下文中为大家展示。52514

这次大型轴瓦专用车床的设计，使我明白了一个机床设计的主要步骤。我先要学习有关机械方面的各种知识，能做到活学活用。然后才能对机床设计这一课题进行研究。分析应该怎样设计机床，怎样计算其中的主要数据，还要涉及到怎么合理利用资源，怎么提高机床加工的工作效率的问题，这些都是我们应该考虑的。学习各种零部件的画法也是其中要学习的一项。这次的毕业设计让我受益良多，不仅充实了自己的专业知识，也让我体会到了自主学习的乐趣，并会把这种自主学习的精神带到今后的学习和工作上面去，充实自己的学习生活。正所谓，活到老学到老。我们都应当追求学习的乐趣，让自己的人生变得充实有趣。这些就是我个人对这次毕业设计的理解和方法还有自己的结论。下面我将为大家具体阐述我在毕业设计中遇到的问题和解决问题的过程，并且为大家展示一个我的毕业设计成果。也请各位认真的阅读。

Abstract Large bearing lathe and spherical used car large bearing inner sphere  and  a machine tool large bush above the cylindrical hole and groove and the end of the. The subject is asked us to design a simple machine can process a large bearing. The two motors to me, is a main motor and a fast motor. I want to design, the main motor and coupling connected drives the gear machine above, so as to realize the machining of internal spherical surface of large bearing effect. And then draw the two auxiliary tool, used for processing large bearing outer spherical and cylindrical hole and slot and end. The whole design is over. Design of concrete will be in the following for the show.

The design of the large bearing special lathe, make me understand a main steps of machine design. I want to learn all kinds of knowledge about mechanical, can do what. Then the design of machine tool was studied in this paper. Analysis of how to design machine tools, how to calculate the main data, but also relates to how to make rational use of resources, how to improve the machining efficiency problems, these are what we should consider. Learn the various parts of the painting is also a learning. The graduation design let me benefit a lot, not only enrich their professional knowledge, also let me realize autonomous learning fun, and make the autonomous learning spirit to the future study and work to go on, enrich their learning life. Is the so-called, live and learn. We should pursue learning fun, let your life interesting. These are my personal understanding and methods of this graduation project has its own conclusion. Below I will for you in detail I met in the graduation design problems and solving problems, and show one of my graduation project results for everyone. Please carefully read the.

Keywords:large bearing, spherical, and spherical, special machine tool.
